Abstract: The kinetics of the polymerization of acrylamide initiated by sodium sulfite in the aqueous solution and CTABmicellar solution is investigated with the theory and method of thermokinetics for the fractional order reactions in this paper.The influence of initiator and CTABconcentrations on the molecular weight of polyacrylamide is discussed.The ratio k2/n in CTABmicellar solution is smaller than that in the aqueous solution.The results obtained show that the rate of formation of radical in the micellar solution was decreased.
